Scientist in the field of fiber preform development for active fibers

Position Overview

We are looking for a researcher who thrives on both conceptual questions and experimental work in the laboratory. The role focuses on the optimization and further development of components for high‑power fiber lasers. The successful candidate will work on fiber preforms using MCVD technology, as well as gas‑phase or solution‑doping techniques for active fibers in the spectral range above 1.9 µm (thulium and holmium doping). This position is part of the Laser Technology (LAS) department, which develops and evaluates specific photonic materials and components and optimizes laser systems in the NIR, SWIR, MWIR and LWIR ranges.

Responsibilities

• Develop, investigate and optimize processes for the realization of fiber preforms using MCVD technology and related doping techniques.
• Realize, investigate and optimize fiber preforms for multi‑clad fibers, polarization‑maintaining fibers and photonic crystal / bandgap fibers.
• Conduct scientific investigation of fiber lasers and evaluate different fiber laser architectures with a multidisciplinary team.
• Work independently on projects in fiber preform research, write reports and publish results in English or German.

Qualifications

• Degree (diploma/master) in physics, chemistry, electrical engineering or equivalent disciplines.
• Knowledge of the realization of fiber preforms (MCVD, solution‑doping, glass working) and related equipment.
• Experience in fiber drawing and basic knowledge of fiber lasers is an advantage.

What We Offer

• Opportunities to work on diverse, exciting projects at the interface between research and application.
• Space for personal scientific development and autonomy for initiating projects.
• Excellent, state‑of‑the‑art technical equipment.
• Motivated, interdisciplinary team.
• Wide range of further training.
• Family‑friendly conditions (flexible working hours, home‑office regulations).
• Discounted Jobticket.

The employment is on a fixed‑term 2‑year contract with the possibility of prolongation or transformation into an unlimited employment. The weekly working time is 39 hours, and the position is also available on a part‑time basis.
